Probabilistic In-Network Caching for Information-Centric Networks
In-network caching necessitates the transformation of centralised operations of traditional, overlay caching techniques to a decentralised and uncoordinated environment. Given that caching capacity in routers is relatively small in comparison to the amount of forwarded content, a key aspect is the distribution of content among the available caches. In this paper, the authors are concerned with decentralised, real-time distribution of content in router caches. Their goal is to reduce caching redundancy and in turn, make more efficient utilisation of available cache resources along a content delivery path.
